Fish Breeding Methods

Fish are a type of vertebrates that live in fresh and salt waters that are spread all over the world, with more than 30,000 species of fish, most of which belong to the cold-blooded category and some to the warm-blooded category. Fish vary greatly in shape, color and size of all kinds, they may be twisted, flat so that they are almost flat, or look like a rock, the smallest of which is one and a half centimeters long, and the largest is the shark and whale ten meters long, we will discuss together in this article ways fish multiply all athat want to know about fish are here www.pets-home.net

About the fish and  Fish Breeding Methods

These fish live in all water bodies on Earth, in the cold waters of the Arctic, and live in almost boiling tropical waters, and in rivers and streams under the surface of the earth, and the type that lives most of its life buried in mud or sand is considered the bottom of the sea.

 

And fish is of great importance to humans, as it is a source of livelihood and food for many, and fishing is done as a kind of sport, while many pet lovers are kept as fish for decoration. It may be harmful to some humans, as it attacks sharks, piranhas and human cases, and the bites of some poisonous fish cause death.

How do fish reproduce?

In most cases, fertilization takes place outside the body of the female fish. Eggs are released from the body of the female fish. In most cases, the eggs are fertilized by fertilization, and in the water the fish are fertilized by sperm.

This method is used in external reproduction in fish, which have a skeleton and they are about 24 thousand species of fish, and there are types of fish that depend on pollination by placing the egg inside the female and the sperm from the male is thrown into the female.

 

And then it can come out of the fish and take care of it outside its body, or the egg can remain in the fish and hatching takes place inside the fish as well, and then the birth of young fish, and this method is used in the internal reproduction of cartilaginous fish, including sharks.

How are fish pollinated?

Fish Breeding Methods

  • Methods of fish reproduction. Most fish reproduce sexually, through the union of the egg collected by the female and the sperm; To form a fertilized egg after fertilization, the genes are then mixed to produce embryos
  • In most of these fish, the process of fertilization is outside the body of the female, where she lays eggs into the water, and then the male releases the sperm on the eggs.
  • Fertilization occurs outside the body and in the water, and about 24,000 fish depend on external fertilization, where thousands of unfertilized eggs are laid and fertilization is then carried out in the water.
  • Certain types of fish on pollination naturally mate between males and females. The female may lay fertilized eggs that she nurtures until they hatch, or the egg may hatch in her body in advance, giving birth to young ready to swim and move. In this way, the group of cartilaginous fish is known as one of the most important types of fish .
  • The method of reproduction in sharks and cartilaginous fish differs in that the number of eggs of cartilaginous fish is much lower and although in general the fish reproduce, their species is quite different and the dominant character of most fish is bisexual i.e. the presence of males and females.
  • But some species have special cases; The only species of many deep-ocean fish is hermaphrodite, because they are few in number and live in separate areas in the water, so it is difficult for them to find a partner if they are male and female, two species that coexist with these species can be directly overlapping.
  • In some species, males and females care for eggs in a different way. Some species begin preparing their nests; They may dig sand on the seafloor, build parts of aquatic plants together, or even blow bubbles of air. The surface of the water may carry some fish eggs inside their mouths, such as: catfish.
  • The life of the egg varies from one place to another and the period required for its hatching in warm water, where the eggs hatch quickly from eggs in cold water, and cold water fish require four or five months in rare cases.
  • Parents may be interested in protecting their young children soon after hatching, but they often leave young offspring to their fate.

How do sharks reproduce?

Sharks that give birth

Sharks that give birth

Methods of fish reproduction, as for sharks, they reproduce by eggs, where the egg sac is placed in their mouths and look for suitable places such as the Port Jackson shark, some of which reproduce by birth, and they are called fish, such as the Pacific River fish. 

For example, the birth of an infant, the size of the fetus may reach five times the size of its mother, and there are some species that keep eggs inside the fetus where the fetus is attached to its mother through a cord similar to the umbilical cord in humans and then gives birth to 20 to 50 small children, such as a soft hammer shark.

Fish spawning methods

There are two different methods of spawning fish by which the fish can be laid to their young, where the spawning can be by giving birth to the young fish (through pollination) or by laying eggs from which the children hatch later (exhale), and the strains can easily swim and search for food directly.

The eggs need some time to hatch, then the young come out from one to ten days to mature and turn into a mature fish.
